The small bowel is a difficult organ to examine clinically and study diagnostically. The SBFT study is an adequate screening tool for evaluation of the small bowel, but if there is a moderate to high index of suspicion of an undetected tumor, enteroclysis is better than upper GI series with SBFT for preoperative diagnosis of such lesions. Based on the above findings, we recommend that any patient with symptoms and findings highly suggestive of small bowel tumor, especially chronic GI blood loss with a negative work-up, be viewed with a high index of suspicion and his case investigated aggressively, using enteroclysis followed by exploration.
小肠在临床上检查和诊断性研究都很困难。小肠钡剂造影检查（SBFT）是评估小肠的一种充分的筛查工具，但如果对未发现肿瘤的怀疑指数为中度至高度，对于此类病变的术前诊断，小肠灌肠造影比上消化道系列检查联合SBFT更好。基于上述发现，我们建议，任何有高度提示小肠肿瘤的症状和体征的患者，尤其是经过全面检查仍为阴性的慢性胃肠道失血患者，都应高度怀疑，并积极进行病例调查，先采用小肠灌肠造影，然后进行探查。
